Rewrite the following equation in log form: 2^2 = 4

We have to write

In log form

To convert exponential equation to log equation, we have to use the following rule

So we will get

or

And that's the required log form .

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
